Abstract: 14,441. Chapman, L., and Knowles, W. H. June 29. Moving - beater and moving - container apparatus.- Lubricators f o r feeding semi-fluid or thick lubricants, such as graphite and oil, are provided with mixing- apparatus. Within a lubricant container 1, Fig. 1, is mounted a pump barrel 3 carried within a housing 4 which is secured to the container by a nut 5. A wormwheel 11 on the barrel gears with a worm 12 on a shaft 13 driven from some moving part of the engine &c. A chambered socket 6 is secured to the housing 4, and carries the delivery pipe 10 communicating with the steam space. A plunger 16 passes through a stuffing- box in the top of the barrel, and is guided in a split stud 43 secured in the cover. A collar 46 passing through the plunger engages a slot in the stud and prevents rotation of the plunger. Collars 37 on the plunger embrace a spherical crosshead 35 carried by a lever 28, which is coupled at one end, by a link 31 to an arm on the wheel 11, and at the other end, is provided with a ball-head 27 engaging cups adapted to slide in a guide-ring 18. The ring 18 is journalled on trunnions fixed to the casing, and can be tilted to any required position. A slotted segment secured to the ring can be clamped to a bracket, fixed to the casing, by a bolt and nut so as to secure the ring in an adjusted position. The lever 28 is carried round with the wheel 11, and receives a reciprocating motion, which is communicated to the plunger, due to the inclination of the ring. In operation, supply and delivery ports in the barrel and container are brought alternately into register during the rotation of the barrel, and the motion of the plunger serves to draw in the lubricant from the container and force it to the parts to be lubricated. A stirring-device arranged on the bottom of the container preferably comprises a number of backwardly - curved, downwardly - inclined blades 55 springing from a boss 56 ; upwardly - inclined blades 57 are carried by the blades 55 and separated therefrom by a wall 58. A worm-wheel on the boss 56 gears with a worm on a shaft driven from the shaft 13 by toothed gearing. A cylindrical screen 64 carried by the container is located above the stirrer. Lubricant is drawn through the screen 64 by the blades 55 and projected upwards by the blades 57. A spiral spring 67 secured to the end of the plunger, and a wire coil 68 carried by the plug at the end of the barrel 3, serve to agitate the lubricant in the barrel and the delivery pipe. Figs. 3 and 4 show means for converting the reciprocating motion of some part of the engine, such as the valve-rod, into a rotary motion of the worm shaft 13. A pinion 88, mounted in a casing 90, gears with a loosely-toothed ring 80 on a disc 81 secured to a worm shaft. Within recesses in this disc are arranged right and left hand springs 86, 87, one end of each spring being fixed to the disc. An oscillating motion is communicated to an arm 91 secured to the axle of the pinion 88, and the ring 80 is correspondingly oscillated. The ring runs freely over the spring 87 in one direction, but, in the other direction, the spring expands and bind the ring and disc together and the worm shaft is rotated. The spring 86 prevents reverse rotation of the worm shaft. According to the Provisional Specification, this gearing is employed when the lubricator is fitted to a locomotive.
